You’ll need:
1.5 yards of waxed linen cord
50 – 70 size 8/o seed beads
a 10-13mm two hole button
scissors
Pic 3: Cut the waxed linen cord into 26" and 19" piece. Fold the longer strand in half. Align one end of the shorter strand with both ends of the longer strand. Fold the excess over the top of the folded piece creating two parallel loops.
Pic 4: Tie a knot about half an inch down from the loops. Snip off the extra fourth strand, leaving 3 equal strands of equal length.
Pic 5: Start braiding the strands. Braid in the beads after an inch or so. Thread a bead onto the outer left strand.
Pic 6: Push the bead against the base of the braid and cross the left strand over the middle. Now thread another bead onto the outer right strand. Push it to the base of the braid and crossover.
Pic 7: Keep a finger at the base of the braid, holding the beads in their place and keeping the braid tight. Continue threading on beads before each strand is crossed over.
Pic 8: Finish the bracelet with another inch of braided cord, measuring it against the wrist. Tie a knot.
Pic 9: Thread on a two hole button - two strands through one hole and one strand through another. Secure it with another knot!
